Abstract

Motion picture coding algorithms for read-only digital storage media (DSM), such as CD-ROM, is studied. For this purpose, it is possible to carry out a non-real-time analysis in advance of encoding and to use the result for improving coding efficiency. In this paper, two methods are proposed for such improvement, prefiltering and background prediction. Computer simulation results show that both methods can improve coding efficiency, approximately 20-30 % over conventional prediction coding, when applied to an image sequence with still camera-work. Moreover, it is clarified that the background prediction also can improve coding efficiency for a panning image sequence.
